Ticks are most active in spring, summer and fall. They can be found in cooler areas where trees, brush, leaf litter and tall grasses provide cover and shade from the sun. Ticks avoid heat and direct sunlight. Ticks feed on blood and will wait for a person or animal to walk by to grab onto. They will then crawl onto the person or animal and search for a suitable spot on the body to attach and feed.
Most NYC residents diagnosed with a tick-borne disease are infected when visiting grassy, wooded areas in upstate New York, Long Island, and surrounding states. However, several types of ticks have been found in New York City. Some of them have tested positive for the germs that cause Lyme disease and other tick-borne diseases.
A range of factors influence tick populations, including weather and available food for hosts, such as acorns for mice. Climate change is leading to warmer average temperatures resulting in longer warm seasons. Earlier spring, hotter summers and shorter, milder winters provide conditions that influence the number of ticks and where they are found. More ticks in more areas, may lead to more people and animals being bitten and infected with a tick-borne disease.

Resources for Educators
The Tick Toolkit is a multi-faceted resource for elementary school educators with materials to teach children about ticks, tick-borne diseases and ways to prevent tick bites. It was created for third to fifth grade audiences and can be adapted for other grade levels.
These toolkit items can be downloaded:
A stuffed "Tick Check Harry" dog with toy ticks can be ordered using the Tick Toolkit Request Form. The lesson plan, bagel handout, Tick Check Harry word match handout and All About Ticks workbook can also be ordered using this form.
If you use any of these materials, take the Tick Lesson Educator Feedback Survey to help improve future materials.
